We have a water erosion crisis. Our problem is that the water that is eroding down the river. When the water flows down the stream it is eroding the mud and messing the bridge up. It is flowing so fast that it is moving the soil down the river and creating a build-up. The roots are also being effected by the water. When the water soaks into the soil, if it packs tight enough it will start making it come trough the soil and the bridge gets effected by it. the bridge gets so wet from the water that it might not be able to stand much longer. Under the bridge is the main place for the water to sit because it holds the water there. There are many different ways that water can erode things.
